Elastic and Inelastic Scattering of 11.2 MeV Deuterons

抄録

The differential cross section for deuteron-nucleus elastic scattering has been measured for N, O, Ne, Mg, Al, S, A, Ca, Cr, Fe, Ni, Cu, Kr, Ag, Xe and Au at the deuteron energy of 11.2 MeV. Measurements were done at 5° intervals from 15° to 165° with relative uncertainty of 3 to 5%. Deuterons were detected by a thin CsI(Tl) crystal whose energy resolution was about 4% so that in almost all the cases inelastic deutrons and protons produced from (d, p) reaction were rejected. The measured cross sections show a pronounced diffraction pattern in light and medium weight nuclei. But the cross sections for heavier elements show a smooth decrease and are smaller than the Rutherford cross sections.
The cross sections of deuterons leading to the first excited state of ²⁰Ne and ²⁴Mg by inelastic scattering have been obtained. However, we could not detect inelastically scattered deuterons in other elements. The angular distributions for ²⁰Ne and ²⁴Mg are explained by the direct nuclear process.
